Nope ... I live in the only two states west of the Mississippi where a law abiding citizen CANNOT own a Class III firearm. Of course, I don't consider Hawaii a "state". It never has been, so why start now .... and all the Bruddah's carry illegally over here, in any case.
In the other state (WA) the Class III prohibition historically dates back to the "Wobblie" union riots of the teens/20's/30's when some Pinkerton dicks went psycho on some union demonstrators with a Thompson or two ... or three. At least that's the story ... so if I go to Idaho or Oregon, presto: rock 'n roll is legal. Were I to do that ... my first two purchases would be a Thompson and a BAR.
I love our gun laws. They really make a lot of sense.
+300 on the BAR damn I bet that would be a riot to shoot (and lug around)
